Hi,
My battery life/indicator has been behaving very strangely since yesterday, so I'm wondering if the battery is dying. I know about battery calibration, and attempting it hasn't solved anything. I haven't flashed any firmware recently.
When I plug in the charger while on, it almost immediately tells me it's 100% charged, but the number displayed will still be something low, like 50ish. When I unplug it, the number stays. It drops extremely quickly, to around 1-2%, then 0% and turns itself off. After turning it on again, it may rise to 10%, but drop again to 0% shortly thereafter. After a couple of times of turning it back on, it will refuse to turn on. Charging only seems to work when phone is off, but even then the charge won't last much more than a couple of hours of idling - no calls, no web, nothing.
I've tried charging to full while phone is off (drained), and removing battery stats via cwm before booting up. Doesn't help.
Is my battery faulty? It's a very sudden problem, and my battery has been lasting me for days before this happened
So, I got a new battery. The problem persists. I've tried a factory reset/wiping battery stats, but it's still that way. Could this be a hardware problem somehow?
Any advice is greatly appreciated!!
Which fimware are you on? In your case I'd go back to a stock firmware from samfirmware.com and test once again. If the problem persits, you likely have a hardware issue and I'd have it swapped for a new phone whilst within warranty.

I'm using tweaky rom, JVS. I'm not too sure what the local firmware is (Singapore), the one I had before I switched to custom was 2.1, and I don't feel too safe flashing bootloaders when the phone is prone to turning off...

yeah, you are absolutely right. Have you tried betterbatterystats? ( http://forum.xda-developers.com/showthread.php?t=1179809 ) It will show you wakelocks when your phone should be idling.
Did it help ?
Mate, out of curiosity I was wondering if your issue got resolved.
Also, you should check what is draining off your battery.
I tried reading elsewhere and found "Battery Monitor Widget" could be useful for you to identify this.
Nope, still same problem. It's not a wakelock issue, because the battery dies /so/ fast. I can literally charge it to 100%, unplug the charger, and in 30 seconds it says 0% and turns itself off. The phone itself isn't running hot or anything, and seems to be just idling. [Edit: To clarify, it also charges to 100% in about 10 minutes or so. I'm guessing that for some reason the phone thinks the battery is 'full' and stops charging, leading to the quick drop. I've no idea what could cause this though]
I'm hoping that maybe it's a software issue now since the new battery isn't working either (the battery is probably a fake since i got it for cheap, but even then it should last at least a few hours before draining), and that the phone is confused with battery voltage levels or something when I put the new one in.
Anyway, I flashed JVU stock, didn't even root, and will be charging the new battery overnight while phone is off. It says 100%, but gonna leave it on charger anyway. Hopefully if I wake up tomorrow it'll be working :/
If that doesn't work, will be flashing DXJV9 (My original firmware was dxj4), and hope that it's the official one here. Then bring it to a service center and act dumb and hope they can fix it i guess...
Service center replaced motherboard. There goes a hundred bucks :/
Today, the strangest thing happened: My phone turned off and when I turned it on, the screen showed the battery icon and the circular animation for half a second and then turned off, and then again showed the same icon and animation and turned off. This looped until I took the battery off. I put another battery with 100% charge and the same thing happened.
I flashed Gingy 2.3.4 with Odin and when I turned it off and then on, the same problem appeared.
As a workaround, I flashed the phone again and don't turned it off.
I don't know what happened or how I can fix the phone. I tried resetting the battery stats and nothing.
PD: In august I bought a spare battery for my Galaxy, and since then I've been using it along with the original battery.
In the last month the phone has been acting strange (only with the spare battery put on): it turned off while still battery had like 40% of charge and when I turned the phone on, it showed 1% of charge. Even though this was strange, I don't think this is the cause of the problem described, as the phone is behaving strange with both batteries.
PD: I have been a happy user of MIUI Rom for several months. I don't think that's the reason of the problem either.
did you try to plug in your charger to the phone and then boot it?
It worked for booting the device, but it didn't solve the problem
Copy your essentials from your internal sd to your computer and format it, then try a reflash with a full wipe if you haven't already...
If that doesn't work I fear its a hardware problem, if you have warranty then send it in after a flash to stock... However it could be water damage somehow, so make sure you have water damage insurance. Moisture can cause problems in rare cases and can all set off the water damage stickers.
Also have a look at the battery bins and the micro usb port they could be damaged. Does the batteries seem to have been damaged?
The 40% issue could be because you need to reset you battery stats.
Good luck
I flashed it several times, wiping, resetting batt stats and everything.
It hasn't been in contact with water, so I don't think that could be the problem. I don't have warranty. Both of my batteries look ok, and the usb port looks ok too.
It seems that I have to take it to costumer service.
Same thing here...
loop after loop. Flashed, reflashed etc. - no joy.
Anyone with an idea?

Hello and how are you?
I recently flashed the latest doomkernel on my phone, installed a rom and all was working fine. However my batter dropped to 0% and now the phone is not booting up. I had it charged for 10 hours (twice) and when I press power button the red light flashes twice. I was not able to imitate a battery removal (power+vol up) so I removed the battery itself, waited and recharged. The phone is detected as a USB device by the pc, but I cannot flash anything since it turns off.
My carrier says this is a broken motherboard/mainboard
Has anyone experienced such issue? any help?
Mainboard is fine. Battery has to low voltage. I think the device cannot charge the battery, when it's turned off. You must charge the battery somewhere else.
my note is rooted.
few days ago i faced a wierd problem. My phone suddenly turn off. I tried to on it but it only show the "galaxy note gt n7000" screen for few seconds and off. Then i tried connect the charger and on it. then it on without problem & battery level shows 87% as it was when phone turn off. then i unpluged the charger and phone turned off immediately after i did so. Now my phone only works when it connect to the charger. But i put my galaxy s i9000's small battery to the note and on it. It works without any problem with that battery.
I checked my note's battery with my friend's note and battery works fine. I put his battery in to mine and turn on the phone. But the problem exists.
But with my galaxy s battery phone works fine.
when the problem happened my phone is in the CM12 lollipop beta 6 rom by Bauner.
I reflash it with stock rom using odin but didn't solve.
Plzzz help....

As i sayed another battery didn't solve the problem. I already tried one.
thank u
What a nightmare. A friend asked if I could try to fix the a T813 which was stuck on the Samsung logo. The reason it ended up like that wasn't clear but I now believe it must have corrupted the firmware because of a battery issue. I am not sure.
Anyway I assumed a reflash would solve everything, but I encountered a number of problems and now I believed it's nearly bricked.
The battery initially charged but the tablet would not turn off. So it ended up staying stuck on the Samsung logo till it discharged. I tried to charge it again when I was going to begin flashing and it wouldn't. I thought maybe the battery had died so I replaced it.
The battery came with 50% charge and seemed fine. I tried to begin flashing and it had some issues to begin with, stuck on initialisation, then it got half way through and decided to fail. Nightmare
Now it comes up with the blue screen saying software failed blah blah blah use Smart Switch to repair and I was able to get into download mode.
However Smart Switch doesn't recognise the device.
I wanted to attempt more firmware flashes but the battery died. Now it will not charge.
It loads the screen and turns off. I have no way of knowing if its charging at all.
Does the battery need software to charge? Or do I have a charger problem? I know if the battery had charge it would only be soft bricked and I could continue to try and fix it, but until I can work out why it won't charge. It essentially bricked.
It might be important to add that the only thing I have to charge this tablet is a s9 phone cable and charger brick which is 5v 2a I think. Is that enough? Because of this the tablet turns on the screen and uses the power its gained showing me the blue screen. I am wondering if I am fighting a battle between drain and charge. Anyone got any advice on what I can do?
